我需要为我的Node Web应用程序创建一个持久的MySQL连接。问题在于,这种情况每天会发生几次:
Error: Connection lost: The server closed the connection.
at Protocol.end (/var/www/n/node_modules/mysql/lib/protocol/Protocol.js:73:13)
at Socket.onend (stream.js:79:10)
at Socket.EventEmitter.emit (events.js:117:20)
at _stream_readable.js:895:16
at process._tickCallback (node.js:415:13)
error: Forever detected script exited with code: 8
error: Forever restarting script for 2 time
info: socket.io started
这是我的连接代码:
// Yes I know multipleStatements can be dangerous in the wrong hands.
var sql = mysql.createConnection({
host: 'localhost',
user: 'my_username',
password: 'my_password',
database: 'my_database',
multipleStatements: true
});
sql.connect();
function handleDisconnect(connection) {
connection.on('error', function(err) {
if (!err.fatal) {
return;
}
if (err.code !== 'PROTOCOL_CONNECTION_LOST') {
throw err;
}
console.log('Re-connecting lost connection: ' + err.stack);
sql = mysql.createConnection(connection.config);
handleDisconnect(sql);
sql.connect();
});
}
handleDisconnect(sql);
正如您所看到的,handleDisconnect代码不起作用。
